Description

[Technical field]

[0001] The present application relates to the field of automotive technology, in particular to puncture-safety wheels. [Background technology]

[0002] When a tire without inner lining and sidewall support gets punctured, the rolling resistance of the punctured tire increases significantly. Rolling resistance is made up of three parts: tire deformation, road surface deformation, and friction between the tire and road surface. This causes the balance of force between the left and right sides of the vehicle to be disrupted, leading to skidding and loss of control.

[0003] If a vehicle is traveling at high speed and a tire without inner rims and sidewall supports suddenly punctures, it usually takes the driver 2-3 seconds to react. By the time the driver reacts, the vehicle may skid widely and enter the adjacent or oncoming lane. At this time, the driver may become nervous and turn the steering wheel suddenly, which causes the bead of the punctured tire to detach from the bead seat of the wheel and slide into the wheel groove, causing the wheel rim to contact the ground and the vehicle to spin out and become uncontrollable, leading to a serious traffic accident. In severe cases, it may even cause a rollover accident.

[0004] This shows that reducing the rolling resistance of a punctured tire can reduce the degree of skidding of a vehicle that has a puncture. If there is less skidding after a puncture, the driver will not be overly nervous, and sudden steering operations can be reduced or avoided, preventing the tire bead from slipping out of the wheel bead seat and sliding into the wheel groove, preventing the wheel rim from contacting the ground, and reducing the incidence of accidents after a puncture.

[0005] The groove on the rim of the current wheel is close to the outer structure of the wheel, and the outer diameter of the groove is smaller than the inner diameter of the rubber tire bead. The role of this groove is to use the small outer diameter when mounting the rubber tire to the wheel, but this groove poses a risk when the car has a puncture. When a car has a puncture, the bead of the rubber tire comes off the groove inward, the rubber tire and the wheel do not rotate synchronously, the wheel spins, and the rubber tire does not rotate due to friction with the ground. In addition, the diameter of the rubber tire on the punctured side becomes very small, so the difference in the mileage between the punctured side and the opposite side wheel becomes large, and the direction of the vehicle is biased to the punctured side, causing a traffic accident.

[0006] Therefore, there is an urgent need for new technological solutions to solve the problems in the current technology. Summary of the Invention [Problem to be solved by the invention]

[0028] The present application will be described in more detail below through specific examples with reference to the drawings.

[0029] In the description of this application, "plurality" means two or more unless otherwise specified. The terms "first", "second", "third", etc. in this application are used to distinguish the objects of reference and do not have any special meaning in technical content (e.g., do not emphasize importance or order, etc.). The expressions "include", "includes", "has", etc. mean that they are not limited to specific units, parts, materials, steps, etc. The terms "upper", "lower", "left", "right", "middle" and the like used in this application are used to facilitate visual understanding by referring to the drawings, and do not absolutely limit the positional relationship of the actual product. Changes in these relative positional relationships are also considered to be within the scope of this application as long as they do not deviate from the technical concept of this application. For purposes of this application, "standard width of wheel body" means the linear distance between the outer edge of the first rim and the outer edge of the second rim.

[0030] Flat tire accidents are random and unpredictable, and once a flat tire occurs, drivers often panic and make mistakes due to lack of experience, which can lead to disastrous accident outcomes. Statistics show that when a flat tire accident occurs while a car is traveling at a high speed of 140km / h, the fatality rate is nearly 100%.

[0031] In order to prevent serious skidding of a vehicle after a puncture, this application provides a puncture safety wheel to solve the problem of the tire coming off the bead seat and the vehicle skidding after a tire puncture of a vehicle traveling at high speed. The results of the impact vibration test and the actual vehicle simulation puncture test show that the puncture safety wheel provided by this application can reduce the traffic accident occurrence rate caused by punctures by about 95%, and the puncture safety standard exceeds the national standard by about 30%. This can effectively reduce the accident occurrence rate caused by vehicle punctures and protect the safety of the driver and passengers. The puncture safety wheel provided by this application has an integrated structure, is applicable to all vehicles, is easy to process and install, and is convenient and safe to use and maintain.

[0032] Example 1 Please refer to Fig. 1. The puncture safety wheel provided by the present application includes a wheel body 1, which has an outer circumferential surface 11 and a first side surface 12 and a second side surface 13 provided relatively on both sides of the outer circumferential surface 11. In one embodiment, the first side surface 12 is an inner concave surface recessed toward the second side surface 13, and the second side surface 13 is formed with a through hole through which the hub shaft of the automobile passes, and the first side surface 12 is formed with a connecting seat 121 that fits the hub shaft of the automobile. The hub shaft of the automobile passes through the second side surface 13 and is connected to the center of the first side surface 12.

[0033] Please refer to Figure 2. A first rim 123 and a second rim 131 are provided on both sides of the outer circumferential surface 11 of the wheel body 1, and a tire seat is formed between the first rim 123 and the second rim 131. The first rim 123 and the second rim 131 have the same diameter, and the diameter of the first rim 123 or the second rim 131 is called the reference diameter of the wheel body 1.

[0034] In order to realize the support and positioning of the tire after puncture, the tire mounting seat is provided with a delamination prevention ring 111. See FIG. 3. The delamination prevention ring 111 is an annular protruding ring provided along the outer circumferential surface 11, and the delamination prevention ring 111 is provided concentrically with the outer circumferential surface 11, and a tooth structure is provided on the surface of the delamination prevention ring 111. This tooth structure is composed of several protruding teeth 1111 and tooth grooves 1112, and the protruding teeth 1111 and the tooth grooves 1112 are provided at intervals, and the protruding teeth 1111 are protrusions extending outward from the surface of the delamination prevention ring 111, and the tooth grooves 1112 are recessed inward from the surface of the delamination prevention ring 111. See FIG. 3. The outer diameter of the protruding teeth 1111 is larger than the bead diameter of the tire that fits into the tire mounting seat. Therefore, when the tire is punctured, the delamination prevention ring 111 on the wheel body 1 provided by the present application can support and hold the tire through the protruding teeth 1111 and the recessed grooves. In particular, the protruding teeth 1111 can hold the tire, and the punctured tire can be held by the anti-detachment ring 111 and continue to rotate together with the wheel, which can greatly reduce the difference in mileage between the left and right wheels and reduce the directional deviation of the vehicle.

The anti-detachment ring 111 of the puncture safety wheel provided by this application is close to the first rim 123 of the wheel body 1, and a first bead seat 112 is formed between the anti-detachment ring 111 and the first rim 123, and the diameter of the first bead seat 112 is smaller than the diameter of the surface of the anti-detachment ring 111. When the tire is punctured, it is held by the anti-detachment ring 111 after coming off the first bead seat 112, and the punctured tire rotates synchronously with the wheel, reducing the skid width of the vehicle and improving safety.

A wheel outer groove surface is formed between the first protruding ring 113 and the anti-detachment ring 111. Since there is one bead on each side of the bead of the tire, when the tire is mounted on the wheel, one bead is mounted on each of the first bead seat 112 and the second bead seat 114.

[0038] In one embodiment, see FIG. 3. A plurality of protruding teeth 1111 and tooth grooves 1112 are evenly distributed on the surface of the anti-snap ring 111. The protruding teeth 1111 are provided on the side of the anti-snap ring 111 close to the wheel outer groove surface, and the tooth groove 1112 is a concave groove with an open end, and the open end of the tooth groove 1112 faces the wheel outer groove surface. The inner diameter of the bottom of the tooth groove 1112 is smaller than the diameter of the first bead seat 112. The diameter of the first protruding ring 113 is smaller than the outer diameter of the protruding teeth 1111.

[0039] In one embodiment, see Fig. 3. The wheel outer groove surface is provided with a second protruding ring 115, a third protruding ring 116 and a groove ring 118 arranged between the second protruding ring 115 and the third protruding ring 116. The second protruding ring 115 is arranged adjacent to the anti-detachment ring, and the second protruding ring 115 is connected to the anti-detachment ring through a first transition ring 117, which is an inclined surface ring, and the diameter of the second protruding ring 115 is smaller than the inner diameter of the bottom of the tooth socket 112.

[0040] The third protruding ring 116 is disposed adjacent to the first protruding ring 113, the third protruding ring 116 is an inclined surface ring, the first protruding ring 113 and the groove ring 118 are connected through the third protruding ring 116, and the diameter of the first protruding ring 113 is greater than the maximum diameter of the groove ring 118. The groove ring 118 includes a second transition ring 1181 and a third transition ring 1182, the second transition ring 1181 and the third transition ring 1182 are respectively inclined surface rings, and the intersection of the second transition ring 1181 and the third transition ring 1182 forms the minimum diameter of the groove ring 118. In one embodiment, the maximum diameter of the second transition ring 1181 is equal to the maximum diameter of the third transition ring 1182 .

[0041] In one embodiment, the intersection of the second transition ring 1181 and the third transition ring 1182 is located on the centerline of the marking width of the wheel body 1.

[0042] In one embodiment, the outer diameters of the first rim 123 and the second rim 131 are equal, and the outer diameter of the protruding teeth 1111 is smaller than the outer diameter of the first rim 123 .

The above-mentioned spokes 14 are strip-shaped, and one end of the spokes 14 is connected to the connecting seat 121, and the other end is connected to the first rim 123.

[0044] As can be seen from the above, the puncture safety wheel provided by the present application is provided with a delamination prevention ring 111, and the delamination prevention ring 111 is provided with a tooth structure that can hold the tire and rotate with the wheel. This tooth structure is composed of a plurality of protruding teeth 1111 and tooth sockets 1112, and the outer diameter of the protruding teeth 1111 is larger than the bead diameter of the tire that fits the tire seat. By using the puncture safety wheel provided by the present application, when the tire is punctured, the bead of the tire falls directly from the first bead seat 112 to the position of the delamination prevention ring 111, and the protruding teeth 1111 of the delamination prevention ring 111 can hold and support the tire, so that the punctured tire can continue to rotate with the wheel. This greatly reduces the difference in the running distance between the left and right wheels, reduces the directional deviation of the vehicle, and even if the vehicle is punctured, it can decelerate and brake while maintaining its direction, effectively avoiding problems caused by punctures during high-speed driving, effectively reducing the incidence of accidents caused by punctures, and protecting the safety of the driver and passengers.
